On the day that LAPD lapel cameras make their debut, we talk about the ratcheting up of tensions between cops and activists.

A Houston-area sheriff’s deputy was shot in the back of the head as he put gas in his patrol car, and the local sheriff hinted that the “Black Lives Matter” movement was making matters worse. At the Minnesota state fair, “Black Lives Matter” sympathizers marched and chanted, “Pigs in a blanket, fry ‘em like bacon.”

African Americans say they have felt threatened by police for years. Now, cops may be feeling that they have targets on their backs.
